有人可以帮助我如何调用方法SendSms(textMessageItems)异步?什么是最好的方法/做法?我假设Task.Run Async-Await可以在这里使用,因为我使用.Net4.5使用MVC4 WebApi。但我想听听专家的意见,因为我是新手。我在我的Web服务器中使用此代码,该服务器位于IIS7中,此方法可能需要一段时间才能处理,因此需要异步处理它,以便响应可以立即返回给调用者。 此外,因为我在for循环中调用SendSms会导致任何问题吗?你认为我应该将它作为集合列表传递然后处理吗?请指教。
using Twilio.Mvc;
using Twilio.TwiML.Mvc;
using Twilio.TwiML;
public class SmsController : ApiController
{
[HttpPost]
public HttpResponseMessage Post([FromBody]SmsRequest smsReq)
{
var response = new Twilio.TwiML.TwilioResponse();
//validation checks..
try
{
if ((txtMessageResponse != null) && (txtMessageResponse.SmsMessageInfo.Count > 0))
{
_smsStagingList = txtMessageResponse.SmsMessageInfo;
foreach (TextMessageStaging prepareTextMessageResponse in _smsStagingList)
{
smsDTO textMessageItems = new smsDTO();
textMessageItems.PhoneNumber = prepareTextMessageResponse.PhoneNumber;
textMessageItems.SmsMessage = prepareTextMessageResponse.SmsMessageBody;
isTxtMessageSent = SendSms(textMessageItems);
//If the messages were sent then no need to set the flag to be updated
if (isTxtMessageSent)
{
txtMessageStatusToBeUpdated = false;
}
}
return Request.CreateResponse(HttpStatusCode.OK, twilioResponse.Element);
}
else
{
//send error response
}
catch (Exception msgProcessingError)
{
//send error response again as processing error
}
finally
{
//set the outbound flag in the table
}
}
private bool SendSms(smsDTO textMessageItems)
{
bool isTxtMessageSent = false;
PushMessageRequest txtMessageRequest = new PushMessageRequest();
PushMessageResponse txtMessageResponse = null;
txtMessageRequest.SmsMessageInfo = new SendTextMessage(); //instantiate the dto
txtMessageRequest.SmsMessageInfo.ToPhone = textMessageItems.PhoneNumber;
txtMessageRequest.SmsMessageInfo.TextMessage = textMessageItems.SmsMessage;
try
{
using (ITextService textService = ObjectFactory.SendSmsMessage())
{
txtMessageResponse = textService.SendSmsMessage(txtMessageRequest);
}
isTxtMessageSent = txtMessageResponse.IsSuccessful;
}
catch (Exception ex)
{
isTxtMessageSent = false;
}
return isTxtMessageSent;
}

我建议您不要使用Task.Run
。 AFAIK,Twilio没有async
API,所以你应该问他们。你当然可以自己编写,例如,基于HttpClient
。
希望异步处理它,以便响应可以立即返回给调用者
请注意async
does not change the HTTP protocol,如我的博客所述。它是possible, but extremely dangerous,在请求尚未完成处理时返回ASP.NET的响应(也是我博客的链接)。
